MATLAB: How to Rearrange a Matrix

Question

I have a matrix that I would like to rearrange into a new matrix.

Below is a simplified problem that I'm experiencing:

Matrix 1:

Column 1(Elements) Column 2 (Stress)

1 3.023

2 43.48

3 4956

4 45687

5 135

6 444

7 7916

8 646

9 6468

10 777

11 6548

12 4979

New Matrix:

Column 1(Elements) Column 2 (Stress)

2 43.48

4 45687

6 444

7 7916

8 646

12 4979

admittedly, I feel a bit stuck about this. Rather than continuing, I’m wondering if I could lean on your expertise and insights to learn how to do it.

Thank you 🙂

Answer 1

% let M be your matrix of two columns
ind = [2 4 6 7 8 12]; % desired indices
new_M = M(ind,:)
